In a forsaken aeon of decay and suffering, man finds himself mired.
Marshes and sucking mud has been a scourge of travellers ever since the primal ancestors of man climbed out of trees on Old Earth. Loose and treacherous surfaces have pulled down feet, cartwheels and wholesale beasts, humans and vehicles since before man’s forefathers invented metalworking. No wonder primitive man dwelling in cold climes preferred to travel and conduct trade by sleigh during winter, so as to avoid rough terrain and mud season.
Throughout the distant past of the Age of Terra, nomads, traders, settlers and explorers all endured hardship and stuck wagons out in the field. Yet the starkest examples of the hopeless drudgery of mired vehicles may always be found among armies on campaign. Here, misery and fruitless toil will be on full display among masses of men and draft animals, as wheels cut deep ruts and then grind to a halt in the wet landscape. Among such marching hosts may be glimpsed raw despair as hundreds of people haul and toil to drag along stuck wagons or machines. Spades will dig into mud and ropes will be stretched taut to rescue wains of wood or steel , and sometimes horses and engine crafts assisting in the recovery will themselves run aground, in a parade of filth to drain all hope.
The humble earth beneath man’s feet hold the power to sprout a cornucopia of food, or destroy his dreams and sink the mightiest of warhosts in an uncaring morass. Great wars have swung from triumph to defeat in the muddy bosom of the soil as weather shifts and the wet season of the land eats giant warmachines with a ravenous appetite. What a tragic toolmaker is man! No ingenuity has ever allowed him to craft an iron steed truly immune to betrayal by the ground itself. No fantastic wain wrought by human hand can ever be safe from drowning in the earthen gullet, swallowed like a god’s unwanted offspring.
Thus the bloodied field itself may vanquish undefeated conquerors, for mud has been the bane of the tank since its first primitive debut during the misty past of the Age of Terra. The wet ground presents a challenge to those cunning minds and able hands that propelled man into the era of engines, and engineers and inventors alike have never stopped grappling with this quest against the mired vehicle. Yet the clever solutions of the Age of Terra paled in comparison to the brilliant inventions of the Dark Age of Technology, for in that blooming time ancient man became the mortal master of creation. His genius climbed to its dazzling peak, and his power and seed spread to twain million worlds and innumerable void installations, as man peopled the Milky Way galaxy with unfettered boldness.
Thus the earthly trinity of Man of Gold, Stone and Iron built a galactic paradise, before Dark Ones of Hell toppled man from his lofty pedestal for the sake of heinous hubris and godless sin. Machine revolt, witches and the horrors of the Age of Strife swept away the great works of the ancients in blood and fire, and Old Night descended upon mankind like a cruel predator. Only crumbs left over from the ancient feast of knowledge could be salvaged from the ashes by those inbred cannibal tribes and superstitious savages that scavenged among the blackened ruins, their minds reduced to desperation for mere survival.
Since then, garbled legends handed down through untold generations speak of wains the size of mountains zooming across the landscape in defiance of gravity, carrying titanic loads while themselves skimming on the wind, light as a feather. Other tales speak of cartwheeling skywagons and soaring trains without magrails. Fragments of the glorious anti-gravitic technology of Man of Gold still lingers among his degenerate descendants during the rotting Age of Imperium, as evidenced by crudely copied repulsor crafts, jetbikes and grav-tanks. One increasingly unusual piece of surviving anti-gravitic technology is that of the grav-jack, an archaic relic prized among Imperial armoured forces for bringing salvation to tanks from running stuck in the ground.
The grav-jack is an almost forgotten piece of technology that was once commonplace among Imperial forces from worlds and large voidholms with an advanced level of tech. The most common use of grav-jacks will see four units, akin to box modules, placed in each corner of an armoured vehicle. Grav-jacks are designed not to make a heavy land vehicle soar into the air, but to lift it out of fields of sucking mud and more alien kinds of morasses that remains the bane of tracked tanks everywhere. Ideally, a light thrust from grav-jacks will lighten the vehicle’s ground pressure enough to prevent it from running stuck on treacherous soil.
Fanciful stories exist of more advanced forms of grav-jacks allowing ground-bound vehicles to leap over walls and trenches akin to certain archeotech pieces hoarded by upper caste noble houses, but such ostentatious models have never been seen in mass produced Imperial military service. Instead, the grav-jack is a humble form of skimmer technology able to raise mired vehicles out of mud and marshes, its melody of a deep bass thrum. Certain variant patterns of the grav-jack is more akin to a jet exhaust than unmoving grav plates, their turbines’ hot lift boiling mud, slinging stones and clapping quicksand about in noisy and violent fashion. The anti-gravitic suspensors of grav-jacks have a limited lifting time, and they usually need to be recharged via the vehicle’s batteries over a long period following use. On lengthy campaigns in the field with supply difficulties, the suspensor fields alone will have to suffice, without the boosted lifting power of auxiliary jets drinking fuel.
Tech-adepts of the Adeptus Mechanicus believe the various grav-jack variants found by Explorators in Standard Template Construct hardprints to have originally been designed for the automatic self-lifting of logistical containers on and off means of transport. Yet whatever the forgotten purpose of this peculiar tech of the ancients, its employment within the Imperium of Man has primarily been that of forcing mired tanks out of seas of mud, crystalline sand seas and exotic swamps. Here, it has allowed heavily armoured vehicles to extract themselves from the morass of their own power, ideally without the need for tractors, horses, teams of men pulling at ropes, groxen haulers or recovery vehicles.
The first grav-jacks were used sporadically among the eclectic Imperial forces of the Great Crusade, yet the systematic production and deployment in the field of grav-jacks occurred first three millennia after the Archtraitor nigh-on slew the God-Emperor in the skies above Holy Terra. Let us examine the rise and decline of this dutiful machine spirit.
The self-propelled mud extraction system of the grav-jack saw its heyday in the Imperium’s golden age of the thirtyfourth millennium, as a reasonable compromise between the high costs and technical difficulties of manufacturing grav-tanks, and the enabling upswell of Imperial fortunes at the time. While entire ordinary armoured units of Imperial Guard equipped with grav-vehicles was an unachievable goal even at the zenith of Imperial civilization during the Forging, the flourishing of this silver age of the Imperium still allowed for many regiments to equip their armoured vehicles with grav-jacks. Thus, some terrain-ignoring advantages of skimmer technology were bestowed upon land vehicles in a luxurious investment that saw Imperial armour able to overcome horrid mud seasons, quicksand and more exotic forms of mires on alien worlds.
For a while, Imperial recovery following the Scouring seemed destined to last, and the increasingly commonplace procurement of sophisticated kit such as grav-jacks for Astra Militarum vehicle parks was a testament to the robust state of His Divine Majesty’s astral domains. Yet such advanced production and issuance of equipment could not stand the test of time, as the Imperium aged, and aged badly. As Imperial fortunes worsened, technological knowhow and sophisticated production facilities were lost to a maelstrom of regression, warfare, cutbacks and ever cruder redesigns to meet the voracious demands of unending total war.
Grav-jacks may represent a technological regression from the ordinary heavy grav vehicles of the Dark Age of Technology, yet the ordinariness of grav-jacks in Imperial armies during the thirtyfourth millennium was nevertheless a mark of success, both in terms of economic health, industrial capacity and technological grasp. Grav-jacks are ultimately a practical luxury item, only sporadically seen during the Great Crusade, becoming a commonplace sight at the height of the Forging, and dwindling ever more rare in the long decay since the Age of Apostasy.
Nowadays, many grav-jacks that remain in service are prized relics of the better past, festooned with precious metals and holy liturgy, their activation requiring meticulous ceremonial rites and propitiation of the venerated machine spirit inside. As with many STC pieces of tech, the grav-jack is rugged and capable of impressive longevity if properly maintained. These ancient pieces of tech are usually reserved for command vehicles or similarly revered rides with a storied combat record, and more than a few dubious personal escapes from the battlefield have been pulled off by the leaders of armoured units who got hopelessly mired in mud or worse. The rare grav-jack is nowadays more commonly found in the armouries of Adeptus Astartes chapter and in the armies from forgeworlds of the Adeptus Mechanicus, or even in noble garages stuffed with the best that money can buy, yet the employment of newly made grav-jacks within the Astra Militarum has not yet gone fully extinct.
By the grace of our Lord and Saviour, some few production lines for grav-jacks still remain active throughout the vast breadth of the Holy Terran Imperium, yet the increasing difficulty of processing raw materials for making grav-plates, and the rot in the understanding of building grav-engines mean that the output of production lines is destined to continue to wane. As with everything in the Imperium of Man, demechanization and loss of technological hardware and scientific knowledge grinds ever worse, in a downward spiral that is destined to drag the human species with it into oblivion.
Some strange patterns of grav-jacks have been observed on heavy vehicles belonging to the Leagues of Votann, which is unsurprising given the shared technological heritage, yet retained higher tech level of the reclusive Leagues compared to the Imperium of Man. Such League grav-jacks tend to sport crash bar cages and are advanced enough to act as grav-chutes for large vehicles making landfall from starships, dampening their entire descent through atmosphere drastically enough for the vehicles to make it to the ground without damage. Nothing of the kind has ever been recorded among Imperial patterns of grav-jacks, and the few tech-priests who have ever witnessed such a spectacle of smooth planetary deployment can only wring their mechadendrites out of marvel and envy.
Turning back to the shambolic wreck of human interstellar civilization that is the Imperium of Man, we may note that wheeled armoured vehicles are more easy to maintain than tracked ones, and thus better suited for expeditionary forces with limited shipping capacity. A most recent trend within parts of Imperial industry is that of calls for major replacement of tracked vehicles with wheeled vehicle models, in yet another potential cutback and retardation of Imperial military technology. It remains to be seen if such an etiolated adaptation will take place, since fivehundred generations of proud tracked tankist traditions is a formidable obstacle to overcome in such a parochial realm as that of the Golden Throne.
Come what may, grav-jacks are dwindling relics, reverently maintained and newly produced in small numbers by a scarce few production lines across the galaxy. Grav-jacks are usually earmarked for prestigious elite formations such as Tempestus Scions, Astartes, Sororitas and Inquisition, with some production rate being hoarded by forgeworlds for tracked, wheeled and legged Mechanicus vehicles. The original designs for grav-jacks from the Dark Age of Technology were relatively simple affairs, primarily meant for moving freight containers, yet even such rugged anti-gravitic tech is slipping from the stiff fingers of Imperial possession.
The grav-jack is in truth a humble piece of equipment, made to repulse gravity and defy the mud season. It could be described as a halfway house between a landbound tank and a skimmer grav-tank, yet even so it has proved to be an overengineered luxury item among Imperial forces, and it has shrunk from an ordinary sight among better armoured regiments, to a rare treasure. Ever shrinking in number, the grav-jack is a precious artefact from better times. How many hundreds of thousands of Imperial tanks and armoured vehicles would not have been saved from the hungry landscape of uncounted battlefronts, had they carried grav-jacks? How many crude battlebeasts of steel would not have been operational, rather than abandoned mired in the field, had this rotting star realm not hunkered low in abominable ignorance?
This deteriorating state of affairs can be met with prayer alone. And so millions upon millions of Imperial vehicle crews will include an old tankist prayer to relevant Imperial saints for salvation from the quagmire, the trapping ground, the quicksand, the crystafields and the sucking clay. Justus Extremis. Armouricum Mortis. Imperius Metallus.
Some rare few of the more clear-eyed yet traumatized armoured vehicle crewmen will even include a sorrowful line to this effect in their prayers, even as they beg for impossible forgiveness from the Master of Mankind for the deviant words escaping their malcontent lips: We created nothing of our own, and everything we took from the ancients we distorted.
Thus the Imperium exists to be a terrible lesson to others, an edifice of counterproductive terror, sclerotic bureaucracy and demented grasp of science and technology. Instead of effectivization and better machine systems, the Imperium will have machine breakdowns and replacement with ever cruder machinery and human muscle power. For when output flags and the products degrade century by century, the callous masters of the Imperium know that they must increase input by throwing more bodies at the problem. Thus man has been reduced from an affluent, adventuresome and leisurely master of knowledge, to a hollowed-out wretch doomed to manual drudgery.
Lo, how the mighty have fallen!
Behold the teeming masses of mankind, in all their hunger, their disease and their parasitic infections. Their lives are nothing but vast numbers in a broken equation to feed the meatgrinder. This travesty of human destiny is lorded over by a monstrous tyranny headed by the High Lords of Terra, who themselves are uncomfortably aware that this colossus on feet of clay cannot last, yet reform is more likely to kill the Imperium than to cure it. And so the astral dominion of the Imperator remains hidebound and fanatic, more devoted to its own paroxysms of aggressive myopia than to its sacred duty of preserving the human species.
This, the last strong shield of mankind, is also its demented jailor and hostage-taker. This, the final bulwark of humanity, is also its doomed dead-end, bereft of answers. This, the defender against the outer terror, is also the savage perpetrator of inner terror. This, the fanatical upholder of man’s legacy technology, is also the rotting grave of its knowledge and hardware, the squanderer of all human potential on a million worlds and uncountable voidholms scattered across the Milky Way galaxy.
And so we see that mankind during the Age of Imperium has not only lost everything, but it does not even remember what it has lost.
Such is the state of the human species, in a time beyond hope.
Such is the baleful fate that awaits us all.
Such is the death of a dream.
It is the fortyfirst millennium, and there is only dementia.
